' ,1aea m. 1a,, was 1 zipplication'filed July 12, 1907. Serial No. 383,397.

To all whom it may concern:

{Be it known that I, \VILLIAM H. FOTHER- .for, and has for its objectto provide an exceedingly simple and effective construction by which the stud pins of all classes of ma nes, especially heavy machinery, such. as locomotives, marine engines and the like may be firmly set in their-bearings andfso bushed as to reduce the wear thereon, and when it is required to compensate for such wear this is 'done by setting up the nuts thus overcoming the many disadvantages which have heretofore been experienced in I this class of work.

Vith these ends in view, this invention consists n the details of construction and comblnatlon of elements hereinafter set forth and then specifically designated by the claim.

In order that those skilled in the art to which this invention appertains may under-' standhow to make and use the same I will describe its construction in detail, referring by letter to the accompanyin drawing forming a part of this specification, in

Which Figure 1 is aside elevation of a locomotive rocker bearing showing my improved stud bearings set therein. Fig. 2, a section of the vupper portion of the bearing and split bushlng, the stud pin being left in elevation with the exception of a small part thereof which is broken away to clearly show the arrangement of the wedge kev therein, and Fig.3, a-

p'erspective of the split bushing. y

In carrying out my invention as here em-.

' bodied, A represents the bearing. which may be of any designer for any purpose having a straight hole formed 'therethrough in which is fitted the split bushing B, the-latter being tapered as'clearly shown in Fig. 2 hav-' ing the slots a and 6 formed therein from opposite ends as clearly shown inF 3.

0 represents the stud pin wh1ch-1s shouldered and has a tapering shank C, said tapering shank being adapted to fit snugly within the split bush1ng, the collar D fitting the shank and thus firmly holdthe latter in place. To prevent the nut E from accidcntally backing off ajam nut E is also' threaded upon'the shank and as a further precaution to prevent the moving of "these nuts a wedge-shaped key F is set in a cor responding slot formed in the end of the shank, and said key is prevented from being accidentally displaced by a cotter pin G l)e- 7 ing passed through one of H formed in said key.

From this description it will be seen that a stud pin may be firmly set in its bearing the series of holes and yet when it is desired to remove the same this can be readily accomplished by the removal of the key' and thenuts after which the shank may be driven out of thebearing, and in locomotives and, like work this is of great importance since these stud pins become loose from Wear and often breakofi' requiring considerable time and labor to-remove the old pin-and substitute a new one, andwhen a pin of ordinary construction commences to ,Wear in its bearing the bearing 'must be reamed out for the setting of a new pin Whereas by my improvement any wear"- which may take place is readily compensated for by forcing the split bushing'through the nut and bearing, and on account of the shank being tapered this inward forcing of the bushing will cause it to jam against the thus securely holding the pin in place.

Of course I do not wish to be limited to the" exact details of. construction here shown as these may'be varied within reasonable limits without departing from the spirit of my invention. Y

"Having thus fully described my-invention, what I claim.as new and useful, is-' The herein described combination of a bearing having a straight hole therethrough, a split bushing cylindrical upon its outer: surface and tapering uponits inner'si'n'face, a stud pin having a tapered shank formed therewith, said shank adapted to fit within said bushing, a collar fittedup'on the shank and bearing against the shoulder of the stud.

shank and'adapted ti) jam the split bushing therein, and a cogter pin adapted to fit'within one of said holes for preventing the accidentall displacement 015 the key, as specified.

In testimony whel qaf, I have hereuntb affixed my signature in the presence of two subscribing witnesses. I
